Be it know-n that I, firmer-A. WISE 001), a citizen of theU-nited States, residing at New York, in the county of New York and State of New York,have' invented'a new and useful. Metal-Supplying Device, of

. which the fo-l'lowing is' a specification.

This is a division of my patent on a-mold for stereotyping and'means for supplying metal thereto, Serial No. 790,071-fi'led Sept. 16, 1913, patented May-21, 1918, No. 1,266,740.

This-invention relates-to stereotyping apparatus, particularly ofthat kind in which the parts are operated by powersuch, for ex ample, as shown in my-application, Serial No. 726,239, filed October 17,1912. newed Oct. 13, 1919, Serial 330,520) Patent Ito-1,341,608, of 'May :25, 1920, I do not claim herein the subject matterthereof.

The, principal objects of the invention are to'provide a construction forthispurpose with improved means for delivering I cast plates, discarded tails and pigs of metal into the meltingpot timed with I'GSPGOtlllO the operation of thewpumpso as to keep the supply proportionate to the amount of metal discharged; to provide for moving-the tails on their straight edges throughout their course of travelafter theyare severed; to provide the, gravity chute down which they slide with projections so placed as to turn the tails around while still inthe chuteyto 7 provide improvements in the elevator for this invention thereto.

Fig. 2 is an end-view of the same with the melting potin section to show interior construction. V

Fig. 3 is a plan of the mechanism for operating the parts.

Figz' i is an end view of the portion of the mechanism for feeding metalto the melting pot, and

- Fig. 5 is a sectionalview 'on the line 5 5 thereof.

The invention is shown as applied to a stereotype plate casting machine like that shown in my co-pen-ding application for patent on a machine for casting-and 'de'liven mg curved stereotype printing plates, filed on the 16th day of September 1913 Serial No. 790,070, patented December 3,-1918,,No..

1,286,479. r Referring first to Figs-1 and 2,-it will be seenthat a frame 10 is shown on which-is a vertical upright core 11,- a movable segmental back l2-and a melting pct 31 for supplying the pot with metal.

. For the purposeqof operating the parts a motor 40 is shown operating amain shaft 41 in any-desired way. This 'shaft'in; turn I .preferably operates the mold, pump and-finishing'mechanism.

Also-connected with the main shaft 41, I

have shown a shaftj li provided :with'; a

handle i=5 for rotatingthe parts by hand and a shaft 46 connected to operate a shaft 47 having right and leftworms48 thereon to operate the elevator as will appear-hereinafter.

On the-cam shaft 12 is a cam 50 which operates a cam roll- 51. This roll is mounted on one arm of a two-branched lever '52 which is pivoted to swing loosely oni-a shaft 53 supported by the frame. The other arm of this lever'is connected by a studfiiwith an arm. 55 alsopivoted looselyon thesh-aft 53 and pivotallyconnected by a link 56 with a nut 57, which is movably mounted on a lever 58. This lever is keyed-to the end of a shaft 59. Onthe shaft 59 is an'ar-In 70 which by-a. link'71 is connected with-a piston rod 172 to-the bottom of which is secured the-piston 32.

F or the purpose of feeding the melting [pot with metal the followingmechanism'is ;provi ded. On the frameis a chute 80 for receiving the tails T whichare severed from the plates by the finishing mechanism (not shown). While being. finished the plates P areflheld on the inclined-finishingsarchor support 79. The tails T slide down this chute in the position indicated at the top of F i a on their straight edges.

ne advance corner of each one engages a projection 81 on one lower side of the chute. This causes the tail to be turned around a quarter of a turn so that one of the straight edges is foremost. Then in this po sition it slides down an incline 82 which forms a part of the chute and which is at an angle to the chute 80, so as to be less abrupt. At the. bottom of this incline one advance corner engages a projection 83 on the same side, as indicated in dotted lines in Fig. 4;. This causes it to turn again. so that one of its curved edges is foremost. Thus it has been turned half way round end for end. Then it slides by gravity over an incline Set into a conveyor by a fixed plate 88 which turns it to bring its straight edges parallel with the conveyor.

The conveyor is shown as located in an inclined casing 85 provided with two separate bottoms 86 in the plane of the incline 84.

The conveyor is shown as comprising two endless chains 87 which are operated by the two worms 48 and worm wheels 98. The outer strands of the chains pass upwardly on the outsides of the bottoms 86 and the inner strands pass downwardly between these bottoms.

The two chains are provided with projections 89, kept inregistration and so arranged that-two of these projections pass upwardly on the outer strands together. Therefore, they engage the two edges of theplate and cause the plate to travel upwardly on its straight edges to the top of the conveyor by which it is dumped over into the melting pot. The chains pass over sprocket wheels 90 and 90*, those at the top located over the melting pot.

The projections on the inner strands of the chains coming down at the center do 7 not interfere with the ascent of the tail as they comev within its concavity. It will be understood, of course, that these chains can be used to elevate used plates placed in them by hand and in practice the chains are run at such a speed that these plates can be put in alternately with the tails. 4

For the purpose of elevating pigs of metal, the casing is provided with a longitudinal projection 91. along one side of the bottom. This forms with the side wall of the. casing, a passage way along which the pigs are elevated by one chain.

Although I have illustrated and described only a single embodiment of the invention,

I am aware of the fact that many modifications can be made therein by any person skilled in the art without departing from the scopepof theinvention as expressed in the claims, therefore I do not Wish to be limited to all the details of construction herein shown'and described, but what I do claim is 1. The combination with an inclined sup- 7 port for castings, and a pot for supplying metal to the mold in which the plates are cast, of means for delivering the severed concave castings from said inclined support by gravity on their straight edges turning them part way around therein while still resting on their straight edges and elevating them into the pot.

2. The combination with a receiving pot, of an endless chain for delivering metal pigs thereto, a casing in which said chain is located, and a projection along the bottom of the casing and spaced from the side walls thereof near the descending strand of the chain and between the two strands form ing a channel with the side wall for pigs of metal while being moved upwardly by thechain.

3. The combination with a receiving pot, of an elevator for delivering metal thereto comprising a pair of endless chains having all four strands in the same plane, means for moving the outer strands of said chains upwardly toward the pot at equal speeds, and projectionson said chains in registration with each other for engaging the metal. pieces to be elevated.

4:. The combination with an inclined conveyor delivering upward, of an inclined bottom therefor between the strands of the conveyor, and a chute having an inclined bottom in the same plane as the inclined bottom of the conveyor delivering downwardly to the bottom of the conveyor.

5. The combination with an inclined conveyor. of an inclined bottom therefor between the strands of the conveyor, and a chute having an inclined bottom in the same plane as the inclined bottom of the conveyor, and having meansfor delivering curved tails on its inclined bottom in a predetermined. position.

6 The combination with an inclined conveyor. of an inclined bottom therefor between the strands of the conveyor, and a chute having an inclined bottom in the same plane as the inclined bottom of the conveyor, having means for delivering curved tailson its inclined bottom in a predetermined position, and a support for the tails at the top of said chute.

7. The combination with an elevator for the tails of stereotype printing plates, 'of an. inclined chute for delivering the tails thereto, said chute having a projection extending inwardly from one side thereof for engaging the edge of a descending tail and turning the tail around in the chute.

8. The combination with an elevator for V thereto by gravity, said chute having a projection extending inwardly from one side thereof for engaging the corner of a descending tail and turning the tail around in the chute, and a second projection below the first for turning the tail around further.

9. An inclined chute for delivering severed stereotype plate tails having a floor on which the edges of the tails rest and having a projection extending inwardly from one side thereof for engaging the corner of a descending tail and turning the tail around on the floor, and a second projection below the first for turning the tail around further on the floor, whereby the tails rest on the same edges all the time.

10. A chute having a continuousinclined floor for receiving and delivering severed stereotype plate tails having a fixed projection extending inwardly from one side thereof for engaging the edge of a descending tail and turning the tail around in the chute on its surface which. rests on said floor.

11. A continuous chute for delivering severed stereotype plate tails having means for turning the tails around end for end while descending in the chute and while moving along in substantially a straight line therein.

12. The combination with an elevator, of a chute for delivering hollow semi-cylindrical articles thereto, and means comprising a projection on the side for ensuring that such articles shall all be presented by the chute to the elevator, in a position resting on their opposite straight edges and with said edges located parallel to the direction of motion of the elevator.

13. In an elevator, the combination of two endless chains cooperating with each other to support the opposite edges of an article, a casing in which said chains are located, and a projection along the bottom of the casing near the descending strand of one chain forming a channel with the adjacent side wall for guiding a smaller article so that it can be moved upwardly by one chain.

14:. An elevator for delivering metal comprising a pair of endless chains with all four strands in the same plane, means for moving the outer strands of said chains upwardly at equal speeds, and projections on said chains in registration with each other for engaging the metal to be elevated.

15. In a conveying device the combination of an endless chain arranged at an inclination for delivering upwardly, a casing in which said chain is located, and a guide along the bottom of the casing at a distance from the side walls thereof located between the two strands of the conveyor, and forming a channel with the side wall near the assembling strand for guiding articles while being moved upwardly by the chain.

In testimony whereof I have hereunto aflixed my signature.
